The present invention relates to new and uselful improvements in toilet bowls and has for its prim-ary object to provide, in a. manner as hereinafter set forth, novel valve controlled ventilat- 5 ing means for removing all odors when thetoilet.

is in use. O

Another very important object of the invention I is to provide a novel construction and arrangement whereby the control valve will remain open while ther toilet is in use and until after it hasbeen flushed but which will then be automatically closed thereby preventing the withdrawal of air from vthe roomwhen the toilet is not in use.

Other objects of the invention are to provide a ventilated toilet of the aforementioned char- Figure 2 isa horizontal sectional view, takenI substantially on the line 2 2 of Fig. 1, the Seat cover and other parts being omitted. n

Referring now to the drawings in detail, it will be seenthat the reference numeral l designates generally a bowl having in its upper portion and extending entirely therearound a perforated water chamber or passage 2 for flushing said The water passage 2 is connected by a pipe 3 with a flush tank ll. Rising from the bottom of the ush tank el to a point above the' .highest levelreached by thewater therein is a tube 5, the purpose of which will be presently Thetop of thebowl l includes a raised rear 'portionl Ei having formed therein an air intake chamber 'l of substantially the cross sectional shape shown to advantage in Fig. 3 of the draw- .-1' ings. The chamber 'l communicates with the mcunted thereon afloat i3. adapted to be raised by the rising water in the portion 6 of the bowl i.

(Gli. 4-216) I bowl. i and' it will be observed that said chamber is located above the water lpassage 2. A vent pipe t communicates with the chamber 'l at the rear thereof and said vent pipe has interposed therein, adjacent the rear-ofthe bowl l, a control valve 9 of the butterfly type which is provided with an operating crank il).

Pivotallyl connected to the free end of the crank i@ and extending upwardly therefrom through the tube 5 into. the upper portion of the ush tank t 10 is a vertically movable rod ll which .terminates in a downturned upper end portion l2 having The float i3 is tank l after the bowl l has been flushed. The 15 rod ll is operable in resilient guides Ml which "are provided therefor in the tube 5, said guides being substantially in the'shape of the numeral 3, as best seen in Fig. 4 of the drawings. The

guides ill are of suitable resilient wire and are 2O formed, at an intermediate point, to provide a loop l5 through which the rod l l passes.

` Mounted on the rear 'portion lt of the bowl l i are'upstanding guides ll in which a transverse rod'l is mounted for vertical movement. Con- 25 nected to the rod i8 for swinging movement in a vertical pl-ane is a seat i9 and a cover 2li. Coil springs 2l yieldingly support therear end of the seat l@ in elevated position 4on the raised rear Resilient bumpers or 3@ stops 22 support the front end of the seat i9 on the comparatively low front portion 23 of the bowl i. v

Mounted on one end portion of the 'transverse, vertically movable rod it and extending 35 rearwardly therefrom is an arm 25.1. The rod ll Iextends slidably through the rear end portion of the arm 2li and hasl xed thereon beneath said arm and for engagement thereby a' collar 25.`

or the like. o

It is thought that the operation of the invention will be readily apparent from a consideration `of y.the foregoing. When the seat lQ'is occupied the rear' end thereof is depressed against the tension 'of the coil springs 2l thereby movin-g the rod it, 4,5'

together with the arm Zfl downwardly.` .Downward movementI of the arm 2li lowers the rod ll and opens the valve 9, a kfloat lbeing sub1 merged in the water in the nush tank t. it wiu thus be seen that the vent pipe t will be opened and the draft therein will be amply sufficient to thoroughly ventilate the bowl l'. -When the toilet is flushed and the occupant or user leaves the seat 1 i9, said seat, together with the rod l, the arm 2t, etc., islaga-in raised by the springs 2l but the 55 ,Y i3 for closing the Valve 9.

control valve 9 will remain open. until after the flushing operation has been completed and the water in the tank 4 again reaches its normal level. its normal level the rod ll is raised by the float Closed withdrawalv of air from. the room in which the toilet is located throughthe vent pipe 8 will be prevented.

It is thought that the many advantages ofy a ventilated toilet constructed in accordance with the present invention will be readily understood and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction and in the combination` and arrangeconnected to the bowl, manually operable means for rendering said Ventilating means operative, and means operativelyvconnecting the iiushing apparatus to the Ventilating means for rendering said Ventilating means inoperative.
